Intl needed for v. 9

[Uzlopak]

node builds without intl are failing due to this line

https://github.com/sindresorhus/execa/blob/c0b6efc9cbf8fa88398ccc863a8eb554d3a76f93/lib/arguments/escape.js#L41

execa is used by borp @mcollina. borp is used in undici, thus breaking the without intl unit tests.

> borp@0.17.0 unit
> node borp.js --ignore "fixtures/**/*" --coverage --coverage-exclude "fixtures/**/*" --coverage-exclude "test*/**/*"

Hi @Uzlopak,

Thanks for reporting this.

Do you know of a URL to a pre-built Node.js binary without ICU support? So we can test this without having to build our own Node.js binary. I have checked on https://nodejs.org/dist/ and could not find one. Node.js has a way to specify alternative ICU data at runtime, but I cannot find a way to disable ICU at runtime.

Also, do you know, when using a Node.js binary without ICU support, whether the u RegExp flag works, providing \p is not used? That flag has a few additional benefits beyond enabling \p.

@sindresorhus This could be solved using the following code (I will share the code I used to generate that massive RegExp):

const getSpecialCharRegExp = () => {
  try {
    return /\p{Separator}|\p{Other}/gu;
  } catch {
    // Equivalent to the above RegExp, but works even when Node.js has been built without ICU support
    // See https://github.com/sindresorhus/execa/issues/1143
    return

What are your thoughts about this solution, and about the problem in general?

[sindresorhus]

It doesn't make sense to include such a large regex for such an edge-case. I would just go with \s and maybe a few more and note the limitation in the readme.

[ehmicky]

Yes, I have about to suggest that alternative too. I'm going to put up a PR to fix this.

[ehmicky]

@Uzlopak If you don't know of a way to run Node.js without ICU support (except for building a Node.js binary from scratch), could you please run the following code using your setup which does not have ICU support? To make sure it will work before I create the PR. Thanks!

const getSpecialCharRegExp = () => {
    try {
        return /\p{Separator}|\p{Other}/u;
    } catch {
        return /[\s\u0000-\u001F\u007F-\u009F\u00AD]/;
    }
};

const SPECIAL_CHAR_REGEXP = getSpecialCharRegExp();

console.log(SPECIAL_CHAR_REGEXP);
const codepoints = [0, 0x20, 0x2e, 0x7f, 0x0ecf, 0x10ffff];
for (const codepoint of codepoints) {
  console.log(codepoint.toString(16), SPECIAL_CHAR_REGEXP.test(String.fromCodePoint(codepoint)));
}

[Uzlopak]

will check now, currently compiling nodejs without intl.

[Uzlopak]

nope. Seems like the Regex gets parsed in an early stage, resulting in a SyntaxError, so basically breaking the whole execution of the file.

first with normal node, and then with the without intl compiled one.

Node.js v23.0.0-pre

But this works

const getSpecialCharRegExp = () => {
    try {
        return new RegExp('\\p{Separator}|\\p{Other}', 'u');
    } catch {
        return /[\s\u0000-\u001F\u007F-\u009F\u00AD]/u;
    }
};

const SPECIAL_CHAR_REGEXP = getSpecialCharRegExp();

console.log(SPECIAL_CHAR_REGEXP);
const codepoints = [0, 0x20, 0x2e, 0x7f, 0x0ecf, 0x10ffff];
for (const codepoint of codepoints) {
  console.log(codepoint.toString(16), SPECIAL_CHAR_REGEXP.test(String.fromCodePoint(codepoint)));
}

I dont know if string-width is a dependency or dev dependency, but it has some similar issue:

[Uzlopak]

Yep, I only needed to patch execa in node_modules accordingly and now the tests run in undici with borp.

My patch was:

const SPECIAL_CHAR_REGEXP = (() => {
    try {
        return new RegExp('\\p{Separator}|\\p{Other}', 'gu');
    } catch {
        return /[\s\u0000-\u001F\u007F-\u009F\u00AD]/gu;
    }
})();

Hope this helps. I go back to my baby shift :D

This was very helpful, thanks @Uzlopak for going the extra mile in terms of testing. :clap:

string-width is a dev dependency.
